The federal Drug Enforcement Agency has seized the state’s supply of a key lethal injection drug. All executions in Georgia are on hold.

The D-E-A took the sodium pentothal Tuesday over concerns about how it was imported. The state bought it last July from a small supplier in England. It was used to execute an inmate in January.

Patrick Mulvaney with the Southern Center for Human rights is an attorney for death row inmate Roy Blankenship. He says the Georgia Department of Corrections was forced to turn over importation documents in January.

“The DEA has seized the drugs and apparently there is a problem with the importation. So, this is another chapter in this story.”

Sodium pentothal has been in short supply since its U.S. manufacturer quit making it.
